Specification of Letters Patent.

Patented Sept. 3G, 1913.

Application filed February 17, 1913. Serial No. 749,009.

To all whom t may concern.'

Be it known that I, JOHN BEVERLEY MAG- LAUGHLIN, a subject of the Kingof Great Britain, and resident of the city of Ottawa, Province ofOntario, Dominion of Canada, have invented certain new and usefulImprovements in Boots or Shoes, of which the following is thespecification. y

This invention relates to improvements in boots or shoes and the objectsare to give elasticity of step to the wearer, to reduce thefatigue ofwalking and also to Venti late `the interiorof the shoe, and it consistsessentially of a movable inner sole, spring supportedV at the heel andadapted to assist in lifting the heel of the wearer during the operationofwalking.

ln the drawings, Figure 1 is a sectional view through the shoe. Figs. 2and 3 show perspective views of thebottom and top connecting` plates forthe spring.

Referring to the drawings, A represents a boot or shoe, B the outer solethereof and C the heel. y

D represents the inner sole which is loose within the shoe and which, ifdesired, may only extend part way down from the heel. ln accordance withthis invention, this in. ner sole is normally maintained in slight-lyraised position above the heel by means of a stiif Vspiral compressionspring 10 located in a recess l1 in the heel, the downward movementbeing limited by a block 12 on the underside of the movable sole adaptedto engage a shoulder 13 in the recess 11. lt may be found desirable,instead of leaving the spring loosely in the recess 11, to provideconnecting plates 14 and 15 .at the top and bottom respectively, whichare con-l nected to the block 12 and the bottom of the heelrespectively, the said plates having means by which the end of thespring mayV be engaged therewith. Y As illustrated, theV top plate 15 isformed with anV aperture Copies of this patent may 'be obtained for vecents each, by addressing the Washington, D. C. v

16 in which the ends of the spring may be received and a groove orrecess 17 to receive and snugly hold the end of the spring. The bottomplate 15 is provided with a corresponding aperture 18 and recess orgroove 19.

It will be seen that in operation each time the weight of the wearer isthrown on the ball of the foot, the heel will be raised by means of thespring 10. When the weight is thrown on the heel the spring will becompressed. This gives a very desirable elasticity of step and themovement of the sole D serves to ventilate the interior of the shoe.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention, within thescope of the claim, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specification and drawings shall be interpreted asillustrative and not in a limiting sense.

What l claim as my invention is A boot or shoe having a recess in theheel thereof, a loose inner sole, a spring in the recess, a top platehaving a recess and formed with an aperture through which the end of thespring may extend, and a groove or recess adapted to fit and snugly holdthe end of the spring, a bottom plate provided with a correspondingrecess and aperture through which the end of thD spring may eXtend,vanda recess or groove adapted to snugly receive and tit a portion of thespring.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.l
